0.0179 citric acid
Explanation:
0.223 M citric = 0.223 mol citric/L
# mol citric = (0.223 mol citric/L)(0.0801L)
= 0.0179 mol citric acid
Answer:
27g + 33g = 60g
18g + 24g = 42g
Explanation:
The law of conservation of mass states that no matter can be destroyed or created. Because of this, you are simply making both sides equal.

Notice that the chemical equation provides you with information about how many moles of each chemical species takes part in this reaction.
More specifically, you know that
1
mole of solid copper will react with
2
moles of silver nitrate to produce
1
mole of aqueous copper(II) nitrate and
2
moles of solid silver.
So, assuming that you have enough silver nitrate available to allow for all the sample of copper to react, you can expect the reaction to produce twice as many moles of solid silver than you have moles of solid copper taking part in the reaction.
Use the molar mass of copper to calculate how many moles you have in your sample
1.00
g
⋅
1 mole Cu
63.546
g
=
0.01574 moles Cu
According to the aforementioned mole ratio, the reaction will produce
0.01574

0.03148 moles Ag
Finally, use the molar mass of silver to convert the number of moles to grams
Number of moles = 78.41
<h3>Further explanation </h3>
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
4.72 x 10²⁵ atoms of a substance, then moles :
will tell you the subshell type, so you are dealing with a d orbital.
ml will tell you the orientation of the orbital, there is no distinction between the orbitals so -1 doesnt specifically mean anything.
